cat#  27C101AG   1 MBIT EPROM

HN27C101AG Series / HN27C301AG Series

131072-word × 8-bit CMOS UV Erasable and Programmable ROM


The Hitachi HN27C101AG/HN27C301AG is a 1-Mbit ultraviolet erasable and electrically programmable
ROM. This device is packaged in a 32-pin dual-in-line package with transparent lid. The transparent lid
allows the memory content to be erased with ultraviolet light, whereby a new pattern can then be written
into the device.
